There are two types of afferent neurons found in the cochlear nerve : Type I and Type II . Each type of neuron has specific cell selectivity within the cochlea.

They originally believed that the potential originated from the cochlear nerve, but it was later discovered that the response is non-neural and is cochlear in origin, specifically from the cochlear microphonic ( CM ).

There is no cure or restoration capability if the damage becomes permanent, although cochlear nerve terminal regeneration has been observed in chickens, which suggests that there may be a way to accomplish this in humans.
24.
The cochlear nerve spans from the cochlea of the inner ear to the ventral cochlear nuclei located in the pons of the brainstem, relaying auditory signals to the superior olivary complex where it is to be binaurally integrated.
25.
The volley theory, in which groups of neurons cooperate to code the temporal pattern, is an attempt to make the temporal theory more complete, but some frequencies are too high to see any synchrony in the cochlear nerve firings.
26.
Cochlear implants bypass the normal hearing process; they have a microphone and some electronics that reside outside the skin, generally behind the ear, which transmits a signal to an array of electrodes placed in the cochlea, which stimulate the cochlear nerve.

There is some research investigating the ability of new axons to grow into the Organ of Corti; Engraftment and differentiation of embryonic stem cell-derived neural progenitor cells in the cochlear nerve trunk : growth of processes into the organ of Corti, Auditory hair cell explant co-cultures promote the differentiation of stem cells into bipolar neurons .-- JWSchmidt 14 : 30, 20 December 2006 ( UTC)

The sound waves vibrate the tympanic membrane ( ear drum ), causing the three bones of the middle ear to vibrate, which then sends the energy through the oval window and into the cochlea where it is changed into a chemical signal by hair cells in the organ of corti, which synapse onto spiral ganglion fibers that travel through the cochlear nerve into the brain.
